This multi-ring refillable binder features a sleek contemporary exterior design with durable, precision steel binder rings. Made from a unique proprietary process, the polypropylene cover is rigid to protect the contents, yet lightweight for easy transport. A unique center mounted, multi-fold spine allows the binder to lay perfectly flat during presentations. Also available in a Mini format with a narrower spine, allowing for a sleek, slim profile for presentations using up to 20 pocket sleeves. Both formats are designed to be used in conjunction with Art Profolio Polyglass Pages refill sheets and Art Profolio Multi-Ring Mounting Boards. .
